I was approached today by somebody wanting to buy 52outs.com. I bought it about 4 months ago but it was in use before then. I've not done anything with it, but 52outs.net is starting to get a bit of a community and there's a handful of old links pointing to it. Free domain appraisals are a riotous with an average of $2,400 across 5 appraisals - between $10k and $20. I know it's worth a bit more than face value as it is a very brandable poker name, but I don't know if I can judge it from the ridiculous money some of the Moniker auctions brought in or whether I should be far more conservative in my estimates.
If you bought it then its worth that price to you... depending on multi factors, development, traffic, etc is what the domain is worth. 52 Outs is not a "major" term in regards to gambling... If you have an offer more than $xxx I would tae it and run. my 2 cents
